Preparation techniques

Track blasting is a method of preparation when a concrete floor is particularly dense or where there are large floor areas to be blast cleaned. Mobile Blast Machines can be hired from most plant hire companies. These electrically powered machines fire abrasive at the surface which removes the surface laitance or previous coatings.The abrasive is recycled but the dirt is extracted from the abrasive by a vacuum dust collector, making the whole process clean and effective. Care must be taken when using this type of equipment as it can damage the concrete. If unfamiliar with such equipment we would recommend that a demonstration from the hire company is requested or, in some instances, the supplier can be employed to carry out this part of the operation. The equipment usually requires a 3 phase electrical supply.

Floor Etchant can be a messy process and requires a water supply for washing off the acid and a wet vacuum to extract the contaminated water. Ensure that the etchant is applied evenly; a good method is to use a plastic watering can with a rose attachment, and allow the recommended time required to work. Care must be taken when using such products, and strictly adhere to the manufacturer's recommendations on Health and Safety procedures.
